Herein,
we adopted diffusion-weighted imaging (DWI) with a high fat suppression effect
and high signal-to-noise ratio (SNR) in the cervical region, where magnetic
field inhomogeneity may occur, using integrated slice-by-slice shimming
(iShim), which improves static magnetic field (B0) shimming accuracy. We
examined spinal cord SNR and standard deviation in healthy volunteers and
performed cervical DWI with the conventional B0 shimming method and iShim,
respectively. Furthermore, to verify whether short TI inversion recovery (STIR)
or water excitation (WE) was appropriate as a fat suppression method, we used
DWI with a high SNR at the cervical region by combining iShim with WE.
